Abstract

Background

The outcomes of revision total hip arthroplasty (rTHA) have become increasingly important as their volume increases. Computer navigation, a reliable method to improve component positioning during primary total hip arthroplasty (THA), is not well studied in the rTHA setting. Given that dislocation rates following rTHA are significantly higher than those of primary THA, component positioning becomes paramount in these cases.

Methods

Here, we present two case reports and surgical techniques, one of a 77-year-old man undergoing rTHA for recurrent hip instability following primary THA, and one of a 61-year-old woman undergoing rTHA for severe iliopsoas bursitis who was at increased risk for instability and dislocation given her history of large segment spinal fusion.

Results

Both patients achieved optimal acetabular component positioning after rTHA with imageless computer navigation.

Conclusions

The use of imageless computer navigation in rTHA provides accurate and reproducible component positioning during acetabular rTHA.

在翻修全髋关节置换术中使用计算机导航优化髋臼杯置入：病例报告和手术技术

背景随着翻修全髋关节置换术（rTHA）数量的增加，其结果也变得越来越重要。计算机导航是一种在初次全髋关节置换术（THA）中改善组件定位的可靠方法，但在翻修全髋关节置换术（rTHA）中的研究并不充分。鉴于 rTHA 术后的脱位率明显高于初次 THA，因此在这些病例中，组件定位变得至关重要。方法在此，我们介绍两例病例报告和手术技术，一例是一名 77 岁的男性因初次 THA 术后复发髋关节不稳定而接受 rTHA，另一例是一名 61 岁的女性因严重的髂腰肌滑囊炎而接受 rTHA。结论在rTHA中使用无图像计算机导航可在髋臼rTHA中提供准确和可重复的组件定位。

期刊介绍： Arthroplasty Today is a companion journal to the Journal of Arthroplasty. The journal Arthroplasty Today brings together the clinical and scientific foundations for joint replacement of the hip and knee in an open-access, online format. Arthroplasty Today solicits manuscripts of the highest quality from all areas of scientific endeavor that relate to joint replacement or the treatment of its complications, including those dealing with patient outcomes, economic and policy issues, prosthetic design, biomechanics, biomaterials, and biologic response to arthroplasty. The journal focuses on case reports. It is the purpose of Arthroplasty Today to present material to practicing orthopaedic surgeons that will keep them abreast of developments in the field, prove useful in the care of patients, and aid in understanding the scientific foundation of this subspecialty area of joint replacement. The international members of the Editorial Board provide a worldwide perspective for the journal''s area of interest. Their participation ensures that each issue of Arthroplasty Today provides the reader with timely, peer-reviewed articles of the highest quality.
